A stop pin 2, and Fig. e is an isometricl detail of aWise in th@ 'bracket 26 and is urgedl ,for- 105 31 on the outside of thebracket limits the movement of the drum. rllhe forward end of the drumis notched to provide a pair of spaced lugs or jaws 32 which are adaptedto receive between them a rigid key 33 which is the alarm key for theclock 34. 'llhis clock is of that type commonly known as alarm clockswherein the alarm key, by means ol which 'the alarm is wound, is rotatedwhen the clock mechanism associated therewith has operated to advancethe hour hand to the point selected by lthe setting of the set stemrepresented in the drawing at 35. 'lhis clock, however, has no audiblealarm mechanism associated with the alarm wind stem which carries thekey 33 so that there is no alarm sounded when the key 33 is rotated atthe predetermined time fixed by the setting of the stem 35.

A socket member 36 is preferably. fitted in the opening`27 and receivesthe clock 34 which carries a pin 3T projecting from its side andreceived in a bayonet slot 38 tormedin the member 36. The clock, afterthe alarm key is wound four or five turns and the stem properly set, isentered into the socket so that the pin 37 engages in the slot 38whereupon a further inward and rotary movement locks the clock inposition. rlhe operator need not concern himself about positioning thekey 33 with respect to the notch in the drum. lle inserts the clocksubstantially as illustrated in lFig. 2 and the key may assume aposition transverse to and out of engagement with the notch .in the drumas shown. The inward movement of lthe .clock in inserting the same movesthe drum inwardly against tension of its spring 23 which thereupon tendsto move the same outwardly so that when the key 33 rotates as the alarmunwinds the drum clutches the key so as to be rotated therewith. rlhewire 25 is wound upon the drum 24 and thus moves the lever 21 down torelease the shoe 20. When the shoe is released the sash 7 is free tomove upwardly, which it does under propulsion of its weights 11.

llt will be understood further that so far as the present invention isconcerned it is immaterial whether the device is fitted to an upper orlower sash. 'lhe application to an upper sash is in most instances morepractical and desirable. Where the device 1s applied to a lower sash thesash is preferably underweighted so that it will tend ol itself to moveby gravity from its set position to closed position when released.

When the window is fully open or is set at a point midway open, forexample,

it will when released gain considerable' momentum by the time itapproaches its closed position. rllhis is especially noticeable wherethe sash tits loosely in its casing. The impact of the sash with theupper Leaders illustrated inasmuch as any cushioning-1 means suitablefor the purpose might be used. Exccptin as this device cooperates in thenovel com mation herein `disclosed it forms no part of the presentinvention, but i is described and claimed in the copending applicationof Ralph H. Kingdon,"-Ser-ial` No. 470,041, tiled lilay 16, 1921.

Briedy the device comprises a housing 40 forming a socket in the upperend of the casing. A. compression spring 4l projects downwardly throughan opening in the bottom wall thereof into the path of the sash 7, andis secured to a channel 'frame '42 movable in the housing 40 in whichare mounted a pair of dogs 43. 'lhese dogs are adapted to engageprojections on the side walls of the housing l0 when the. sash 7, withconsiderable momentum, engages the spring 41, the dogs being associatedwith an inertia element which urges them apart into engagement with theprojections against tension of an underlying leaf spring 4:4 normallyholding them upwardlyout of the path of the projections. The spring 41after having been compressed to break the force of the impact expandsagain and moves the sash downwardly a short distance, whereupon theaforesaid dogs are retracted by the leaf spring la and moved out of thepath of the projections so that the window on its return closes, pushingthe spring, frame and parts mounted therein upwardly into the housingd0.

The operation of the device will have become apparent from vtheforegoing description. 'lhe clock 34: is removed from its socket to bewound and set. 'lhis is usually done by the operator when he retires forthe night. He pulls the window down the desired distance at that timeand winds, lsets and replaces the clock. lle, of course, sets the clockfor a time, say one hour before rising, so that the window will close atthat time and permit the room to become heated to a comfortable degreeby the time he must be about. file may, if desired, have a second clockto provide an audible alarm to awaken him, say an hour alter the windowcloses.

The wire 25 is of course wound partly upon the drum 2l by the time thesprmg on the alarm has spent its energy. 'lhe spring 23 under allcircumstances prevents possible slippage ol the clutch provided by thejaws 32, and when the clock 34 is removed at a subsequent time foranother winding and setting, the spring 23 retracts the lever 2l and atthe same time unreels the wire 25 lil@ tessere irom the drum. The springunder these and all other operating conditions places a slight drag onthe drum and thus secures smooth and noiseless operation thereofc F romthe foregoing it Will be seen that the invention provides an especiallyserviceable device of this character, the installation nation with aWindow casing, a Windowl movable therein, means adapte ormally to movesaid Window to closed position, comprising Weights heavier than saidWindowoperating vvithinsaid casing, sheaves in said casing, andlflexible means connecting said weights and said window, releasablemeans for iolding said Window ixedly in open position comprising a shoehinged adjacent a sheave an normally out of engagement therewith, and alever passing beneath said shoe ivoted at one end to the casing andprovied at its opposite tree end with a spring normally urging saidlever upwardly to cause trictional engagement ol said shoe and sheave toprevent rotation ot the latter,
